The Mathematical Physics group at CU Boulder has expertise in Hilbert space theory, quantization theory, random matrices, Poisson geometry, the mathematics of classical and quantum fields, and PDE's ...

This entirely diagrammatic presentation of quantum theory represents the culmination of ten years of research, uniting classical techniques in linear algebra and Hilbert spaces with cutting-edge ...

On the one hand, there has been much progress in understanding how such systems approach thermal equilibrium (ETH and beyond) while, on the other hand, examples have been found of systems that violate ...

and tachyon fields are special cases of quantum field. The math adjustment enlarges a tiny Hilbert space into a larger one to ...

Using quantum gas microscopy, Hilbert space fragmentation and fractonic excitations are observed in a two-dimensional tilted Bose–Hubbard model.
